They also have grappling-hook jetpack things for some reason, and their method of fighting the Titans- humanoid abominations of about 15m in height- involves flying around and taking out massive slices of their necks with giant boxcutters.

I'm currently watching full metal alchemist and I love it. Is Attack on titan any good? I'm assuming since a lot of posts make refernece to it these days that it's very popular. Seen at least 10 posts similar to this one in the past while.

it's one of my favorite new anime- and also one of my new favorite anime. it's ongoing in its first season, but the manga has been around for a while if you want to start reading it. crunchyroll actually has all of the current episodes available for streaming (paid for by ads)

it's less of a shonen action show than it is a science fantasy war drama. many of the episodes early on pick up immediately where the last episode left off, and the characters are still fighting in the same battle/moving along within the same scene that they were shown in previously, mimicking real-time progression of battles. when those arcs aren't being depicted, the show is very tense and dramatic, with escalating plot and a ton of dialogue.

thematically and with regards to the show itself, it reminds me a ton of Gurren Lagann, a mecha anime that Gainax put out in 2007.
